Espressif’s ESP32-C5 is the first ESP32 that talks Wi-Fi on both 2.4 GHz and 5 GHz. Here’s what matters for makers, based on Espressif’s published product information.
What’s new
- Dual-band Wi-Fi 6 (802.11ax). Every earlier ESP32 is 2.4 GHz only. 5 GHz helps in crowded apartment buildings where every flat’s router fights over 2.4 GHz channels.
- A RISC-V core, like the ESP32-C3 and C6.
- Bluetooth LE for phone setup and beacons.
- IEEE 802.15.4 radio for Thread and Zigbee — useful for Matter smart-home devices.
Should you buy one now?
For learning and most projects, not yet. Development boards are only starting to reach Indian shops, prices are higher than the C3 or classic ESP32, and many libraries and tutorials haven’t caught up.
Buy one if you specifically need 5 GHz Wi-Fi or want to experiment with Thread/Matter. Before you do:
- Check that your Arduino-ESP32 core version lists ESP32-C5 support (Espressif’s release notes say which chips each version supports).
- Check the board’s antenna is rated for 5 GHz — a board with a 2.4 GHz-only antenna defeats the purpose.
For exact specifications and availability, check Espressif’s ESP32-C5 announcement and datasheet.
On FlashReady
We’ll add an ESP32-C5 board hub once we can compile-check sketches for it on a released core. Until then, the ESP32-S3 vs ESP32-C3 comparison covers the newer chips you can buy easily today.
